Hi Rabbit,
I also use OX as my broker. My opinion is that they are good but not stellar. Their charts could be a bit better, e.g., it is not possible to get spreads. Some charts, like for DX had errors in them. Since I trade DX a lot, I would call OX to point out the errors and "force" them to fix them. Anyway, long story short, I still use OX but also pay about $35 per month to get quality charts from barchart.com. If you trade spreads of any nature and want reliable charts paying $35 is "nothing."
